I second Sfar' suggestion; you can also control-click a song and the "Convert to ..." option will be one of your choices.
What exactly is the problem using iTunes for large libraries? And why would you want to convert everything to WAV? We've had endless WAV vs FLAC/Apple lossless discussions before, and I'm still clearly in the FLAC/Apple lossless camp. If you think that Apple lossless has problems with album art, just wait until you see the problems you'll have with WAV.
If it were me, I'd stick with iTunes and Apple lossless. You're using an uncompressed format with advanced tagging support and software that is widely used and available on both macs and PC's.
